This paper presents a convenient shortcut method for implementing the Heckman estimator of the dynamic random effects probit model using standard software. It then compares the three estimators proposed by Heckman, Orme and Wooldridge based on three alternative approximations, first in an...

From individual-level data for nine entire cohorts of undergraduate students in UK universities, we estimate the probability that an individual will drop out of university during their first-year. We examine the 1984-85 to 1992-93 cohorts of students enrolling full-time for a three or four-year...

From individual-level longitudinal data for two entire cohorts of medical students in UK universities, we analyse the probability that an individual student will "drop out" of medical school prior to the successful completion of their studies. We examine the cohort of students enrolling for a...

We exploit a rich administrative panel data-set for cohorts of Economics students at a UK university in order to identify causal effects of class absence on student performance. We utilise the panel properties of the data to control for unobserved heterogeneity across students and hence for...
